Fallback from an ajax request that fails.

Hi,
Since onResponseEnd does not seems to be called when an ajax request fails (for any reasons, like a network drop), is there a way to give a feedback to the user that something has gone wrong ?

Thanks a lot.

I'm opening a popup with this code:

window.radopen(

'../PopUp/PopUpLinee.aspx', 'PopUpPiccola');

var oText = document.getElementById('<%=hfdRepartoSelezionato.ClientID%>').value;
var arg = new Object();

arg.IdReparto = oText;

arg.IdTurno = "

1";

radWindow.argument = arg;

}

At this point everithing works fine, but i don't know how to get this arguments when the popuplinee is opened.

I need to put this arguments in two texboxes inside the popup.

Thank you !!!

[Solved] Accessing Edit Form controls

Hello ,

I am trying to access controls in an edit form to render the visibility of certain controls I tried the following but cannot find the controls ,

Public Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As GridItemEventArgs) Handles RadGrid1.ItemEvent

If TypeOf (e.Item) Is GridEditFormInsertItem Then

Dim item As GridEditFormInsertItem = CType(e.Item, GridEditFormInsertItem)

Dim panel As Panel = DirectCast(item.FindControl("Panel1"), Panel)

Dim cmbDataType As RadComboBox = DirectCast(item.FindControl("DataTypeDropDown"), RadComboBox)

If cmbDataType.SelectedValue = "Choice" Then

panel.Visible = True

Else

panel.Visible = False

End If

what would be the proper method to access the controls?

var evt = eventArgs.get_domEvent();

if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

return;

}

if (eventArgs.get_tableView().get_name() == "Models") {

alert('child');

//get the selected datakey value

//

}

else {

var index = eventArgs.get_itemIndexHierarchical();

var key = sender.get_masterTableView().get_dataItems()[index].getDataKeyValue("ID");

CarModelSetKeyValue(index, key);

sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);

menu.show(evt);

evt.cancelBubble = true;

evt.returnValue = false;

if (evt.stopPropagation) {

evt.stopPropagation();

evt.preventDefault();

EmptyMessage remains in place if text is typed in too quickly after render or enable

I am currenlty utilizing the "EmptyMessage" property of a RadTextBox. There is also a checkbox on the page that enables the RadTextBox when clicked. If the user hovers his mouse over the RadTextBox before it is enabled, the user can then type in text and the empty message remains in place in addition to the user input. I was also able to produce this behavior on the demo site (http://demos.telerik.com/aspnet-ajax/input/examples/radtextbox/firstlook/defaultcs.aspx) if I refreshed the page with my pointer over the control and started typing before render is complete. The style also remains in the EmptyMessage style, so when you're typing it is grayed italics text. This behavior is unacceptable to my client. Any fixes/suggestions?

Thanks,
Dean

IIS 7.5 PageRequestManagerServerErrorException

I have had to move a web application from one server to a new one. My intention was to just copy the deployed application over to the new IIS structure. The app code has not changed. Both servers are Windows 2008 SP2: the old server had IIS 7 and the new server has IIS 7.5

I am now getting this error below as a javascript error.

There is a double hop involved and kerberos appears to be working. Fiddler shows no errors. Can you help me with this issue? Why would it not run in IIS 7.5?

Thanks,

How to pass data key fromItemCommand to Selecting event of ObjectDataSource

Hi all,

I need to get DataKeyValue from ItemCommand event of Radgrid and need to pass as input parameter in ObjectDataSource's Selecting event like

obj.EmpID= EmpID (runtime Value from ItemCommand)

e.InputParameters["obj"] = obj

So that the Nested DetailView should be as per that specifc row of Radgrid.

Here i am getting Key from ItemCommand, but unable to pass that key dynamically to ObjectDatasource, because both the events get call at different time interval.

Or i should try different approach.

Please help me on this regard.
